over again, on the same sensitized paper or ribbon. By changing the negative, of

course, any desired number of different prints may be made on the same ribbon. When the photographic prints are made on separate cards, or sensitized pieces of paper,

such will be presented to the negative by movements of the platen against the negative, and when the ribbon is retracted, the print will be dropped from the platen, and preferably, into a suitable receptacle.

This complete machine, in its preferred form, and as illustrated in the drawings, comprises as follows: The framework 1 of the machine is preferably a rectangular I structure, shown as provided with a removable drawer 2 that affords a receptacle for the prints y. Either glass plates or films may be employed as negatives, but, as shown in the drawings, the negative 2 is of the former type. At its rear end, the frame 1 is provided with a vertical extension or pedestal 3, having laterally spaced sides 3* and 3 and also provided, just above the body of the said frame 1, wit-h a large and preferably rectangulanlight passage 4, immediately-in front of which, the negative 2 is properly held by a suitable holder. The negative holder,'as shown in Figs. 1, 2, 9 and 10, comprises upper and lower arms 5 and 6, provided at their free ends with pivoted clamping heads 18 and 7 respectively for engagement, respectively, with the upper and lower edges of the plate. The lower arm 6 is pivoted at 8 to the flange of a vertically extended metal angle strip9, that is rigidly secured to the side 3* of the pedestal 3. The free end of the arm 6 is adapted to be vertically adjusted, by means of a Small screw rod 10 pivotally attached to the outer end of said arm 6, extended downward through a lug 11 of the channel strip 9, and provided with a thumb nut 12 just below the said lug. The upper arm 5 has a threadthe inner flange of the channel strip 9 and exerts a force which serves, in the first instance, to keep the pivot bolt 13 engaged with any one of the notches 16 in which it may set, and in the second place, exerts a force which pivotally'moves the free or inner end of the said arms 5 downward, and thereby causes the pivot head 18 of the latter to cooperate with the pivot head 7 and hold the negative in position. The vertical adjustments of the upper lever 5, as is evident, adapts the levers to be set for proper.

action on negative plates of very greatly different sizes. v

The platen 19 is hinged at 20 to the front end of a horizontal carriage or slide 21. The carriage 21 is arranged to move horizontally on suitable guides 21 formed on the top of the frame 1, toward and from the negative. Mounted to move horizontally on the carriage 21 is a hand piece, or supplemental slide 22 that is connected thereto by a coiled spring 23, the tension of which tends to hold the said hand piece 22 in its most forward position shown in the drawings. This spring, as shown, is directly connected at its ends to anchor brackets24 and 25, respectively, and to the carriage and hand piece. This hand piece, or supplemental slide 22, at its sides, is provided with outwardly and-downwardly extended arms 26, to which the lower front ends of curtain actuating cords or cables 27 are attached. These curtain actuating cords 27 run over guide sheaves 28, and under guide sheaves 29 on the sides of the pedestal 3 and are attached to the lower edge of an upright curtain 30. This curtain 30 may be of the usual or any suitable construction, and is preferably yieldingly drawn upward by a spring wound roller 30 of well known con-- struction. Mounted, preferably in the same manner and working in front of the curtain 30, is an ordinary light screen 31 and a vignetter 32. 'The light screen 31 is preferably located between the curtain 30 and the vigil-- etter 32. The light screen 30, as best shown in Fig. 7, is attached at its upper end to a roller 33, preferably of the spring wound type, and at its lower end, is attached toa pair of cords or cables 34, the lower ends of which are wound upon and secured to a small windless roller 35, journaled in the side plates of the pedestal 3. This roller 35, at one end, is projected through the side plate 3 and provided with a sheave 36. An operating cord or cable 37 is wound upon and secured to the sheave 36 at its front end,

and at its rear end, it is wound upon and secured to an operating sheave 38, shown as provided with a crank or eccentric finger piece 39. Backward rotation of the sheave or operating wheel 38 is normally prevented by a retaining dog, as shown, in the form of a flat coiled spring 39, attached to the bottom of the frame 1 with its free end en gaging a ratchet wheel 40 carried by the said sheave 38.

The vignetter 32 may be, and preferably is, mounted in the same manner as the light screen 31, and the shaft of its operating roller 32 is projected through the side plate 3 and provided with a sheave 40 An operating cord or cable 41 is attached to and wound upon the sheave 40 at one end, and at its other end is attached to and mounted uponan operating sheave or wheel 42, which, like the wheel 38, is loosely journaled to one side of the frame 1, and is provided with an operating crank or finger-piece 43. Backward'rotation of the wheel 42 is normally prevented by a retaining dog shown in the form of a fiat spring 44, secured to one end of the base of the frame 1, and with its free end normally engaging the ratchet wheel 45 carried by the said wheel 42. I

Means have now been described whereby the vignetter or light screen may be drawn down to any desired extent, at will, and held in any one of several positions. Means has also been described whereby the shade will be automatically drawn downward whenever the hand-piece or secondary slide 22 is released and moved to its normal position under the action of the spring 23. Obviously, the said shade will automatically rise whenever the said hand piece and carriage are moved forward. The platen is automatically moved to and from a vertical (position and to and from the negative, un er forward and rearward movements of the carriage 21, through connections substantially the same as those employed in my said prior patent. Also, the platen islocated against the negative by a device substantially like that disclosed in my said prior patent. These devices, in so far as they are similar to the prior devices, will be briefly described. The lever for operating the platen, however, involves an im portant feature of improvement. This lever 46 is intcrmediately pivoted to the carriage 21 at 47 (see particularly Fig. 3), and its lower end is connected to the front end of a short rod 48, the rear end of which works through a lug 49 fixed on the frame 1. A stop in the form of an adjustable nut 50, on the front end of the rod 48 engages with the lug 49 when the crank is moved forward and oscillates the front end of the said lever 46 rearward or toward the negative. As a feature of improvement, this lever 46 is provided with a supplemental section 51 that is connected to the main arm by a sliding pivot guide 52, in such manner that a laterally projecting stud 53 of the said supplemental section may be engaged and disengaged with a lock notch 54 in the extreme upper end of the main arm 46. At its free end, the segmental arm 51 is provided with a wheel or roll 55 that is engageable with the platen 19, to force the said platen into a vertical position and against the negative when the carriage is moved forward. The plat-en is normally retracted by a spring 56 attached thereto, and to the carriage, but this spring is easily overcome by the action of the said lever. Normally, the spring 56 holds bearing lugs 57 of the platen against yielding stops 58 .on the rear sides of the carriage.

The upper portion of the frame 1 immediately in front of the negative is open and is provided with a downwardly inclined guide plate 59 which serves to direct the prints into the drawer receptacle 2, when they are released by movement of the platen, away from the negative, after the print has been taken.

When the supplemental arm section 51 is locked to the main arm 46, said parts operate as a single lever. It is often desirable to see daylight through the negative, and to do this, the shades must be raised-by a rearward movement of the carriage. When the carriage is moved rearward, the platen is normally thrown against the negative so that daylight cannot be seen t-herethrough. But the supplemental arm, when unlocked from the main arm 46 and moved pivotally outward, as shown in'Fig. 6, permits the platen to be moved pivotally away from the negative while the carriage is moved rearward and while the shade is raised, and hence, while daylight is shining through the negative.

The negative 2' is, by the adjustable holder described, held against the front face of the transparent glass plate 60, which, in turn, is held at one of its vertical edges between the folds of a vertically extended U- shaped metal holder 61, which, in turn, is suitably secured to the side plate 8*" of the pedestal 3, and it may be here noted, directing attention particularly to Figs. 1 and 3, that the side plates 3 and 3 of the said pedestal, are shown as in the form of thin sheet metal plates. Also, it will be noted that the said U-shaped holder 61 is off-set forwardly from the front edge of the side plate 3* of the said pedestals 3 so that the vignetter, screens, and the like, may be inserted both in front and atthe rear of the transparent plate 60, and the negative, when-- ever desired. For holding the said vignetter, screens, etc., as just stated, in any desired adjustment, and in anydesired number and arrangement, I provide holders of simple and novel construction. The said holder 61 is made up of a multiplicity of fiat leaf springs 62, of different lengths, and in overlapping arrangement, with their upper ends free and with their lower ends rigidly secured to the lower portion of the U-sha'ped-holder 61, both on the front and rear folds thereof. The vignetters, screens, or the like, are adapted to be inserted both between the longest leaf spring 62 and the folds of the U-shaped holder 61 and between the members of the said leaf springs themselves, and in this way, they are adapted to be frictionally held in any desired adjustment, extended across the negative and plate 60, either at the rear, or at the front thereof, or both at the'rear and front thereof. This provides an extremely simple and efiicient means for holding either a small or large number of vignetters, screens, and the like, in various different adjustments, as required for doing various different kinds of work, well known to photographers.

In'Fig. 11, a print such as a post card, is indicated by the character y and at its lower edge, it is shown as resting upon a rest bar 63, pivoted at its ends to the sides of the lower end of the platen 19, in such manner that it may recede when engaged with the negative (see Fig. 4). To assist in properly positioning these cards on the platen, a frictionally-held gage arm 64 is pivoted to the outer face of the platen and is provided with a gage pin 65 that works through a segmental slot 66 formed in the platen.

In some instances, when a'post card, or other photographic print is to be exposed several times in succession, for the purpose of producing different effects, and to securely hold such prints to the platen for accurate successive exposures,- I provide a holder preferably constructed, as best shown in Figs. 1, 2 and 12, wherein the numeral 67 indicates a bowed thin spring metal clamping plate secured at one edge to the back of the platen and provided with a clamping flange 68 that overlaps the inner and upper portion of the platen, and it adapted to clamp the print g against the felt face 19 of the platen. To assist in effecting an easy release of the clamping plate, it is shown as provided with an upwardly projecting finger-piece 69, that co6perates with a fixed finger-piece 70, on the back of the platen (see particularly Fig. 12).

In Figs. 13 and 14, I provide a modified, improved form of holder adapted to hold a negative, either in the form of a plate or film, and a border mask or similar device for making repeated exposures. ThlS holder comprises a pair of open rectangular thin metal frames 71 and 72 provided with channeled upper and lower flanges so that the said frame 72 is free to slide within the frame 71. The outer frame 71 is adapted to be directly held between the heads 7 and 18 of the negative holding arms 6 and 5, respectively. 7 Obviously, the frame 72 may be slid into and out of position while the frame 71 is held in proper position by the negative holder.

The mechanism so far described, is adapted for use in making prints on post cards and various other individual or separate pieces of printing paper. For making the successive prints on the strip or ribbon of sensitized paper, I preferably provide a device substantially like thatemployed in my said prior patent. This sensitized strip or ribbon g is adapted to be fed from a coil holding casing 7 3 into a cylindrical casing 74:, both of which casings are secured to a frame 75, shown as mounted for vertical adjustments on a pair of thin metal guide strips 76, forwardly oif-set from and secured at their upper and lower ends to the side flanges of the pedestal 3. A spring latch 77 on the upper portion of the pedestal 3 normally engages a transverse upper bar 78 of the vertically adjustable frame 75 to hold the latter in raised position. When this frame 75 is lowered, the ribbon 3 is positioned in front of the negative.

The numeral 79 indicates a vertically adjustable ribbon supporting table mounted in the ribbon case 73.

The ribbon g is arranged to be fed by a pair of cooperating feed rollers 80, suitably mounted on the frame 75, between the cases 73 and 7 1. One of these rollers 80, at its lower end, is provided with a socket 81 (see Fig. 2) which, when the fralne 7 5 is lowered, frictionally engages with the tapered upper end 82 of a short vertical driving shaft 83, mounted in suitable bearings in the frame 1. This shaft 83 is provided with a toothed sprocket-like wheel 8 1 that engages the perforations of a flexible endless belt 85. This endless belt 85 also runs over a second sprocket or toothed wheel 86 that is also mounted on the frame 1, and is shown by dotted lines in Fig. 1. This belt 85 is intermittently driven in a constant direction, from the'carriage 1, through a one-way frictional clutch, shown in Figs. 1, 3 and 5. This friction clutch preferably comprises a spring-pressed lever 87, which is pivoted to a projecting flange 88 of the carriage 21, and has its pivot so located that when the carriage is moved rearward, it will slip over the belt, but when the carriage is returned, it will frictionally clamp the said belt against a clamping flange 89, secured to the adjacent side of the carriage 21, as best shown in Fig. 5. A stop device 90, adjustably mounted on the top plate of the frame 1, (see Fig. 3) varies the normal position and return movement of the carriage 21, and hence, will correspondingly vary the amount of movement that will be transmitted to the ribbon y through the connections just described, when the carriage is given itsret-urn movement, as above stated.

In Figs. 1 and 8, I have shown an indicator comprising a numerically marked ratchet wheel 91, pivoted to the top plate of the frame 1, and with .which cooperates a spring retract-ed ratchet bar 92 mounted to slide on the top plate of the frame 1, and having a single tooth 93 that will move the said ratchet wheel 91 one step of movement for each reciprocation of the said bar. This bar 92 is connected to a rod 9 1 which is given endwise movement under each reciprotating movement of the carriage. The rod 94. is pivotally attached to the upper end of a lever 95 which, in turn, is intermediately pivoted to a bearing 96 on the frame 1. The lever 95 is operated by means of a depending lug 97 secured to the carriage 21. Engageable with the lower end of the lever 95,

is a spring 98 which yieldingly holds said lever in its normal position.

The operation of the above identified machine may be briefly stated as follows: First the negative position against the front face of the transparent glass pane 60 and is held in this position by the clamps 5 and 6. The card if is placed upon the platen 19 in a relative vertical position to correspond with the position of the negative plate a. The mostsuitable way of operating the carriages 21 and 22 can be obtained by the following method. Grasp the handle of the carriages with the right hand leaving the thumb extending downward over the anchor bracket 24:. By forcing the carriages 21 and 22 forward, the platen 19 will naturally move forward and press the card g against the negative plate 2. This forward movement Wlll also raise the light screen 30, thus per mitting the rays of light to be cast upon the negative plate 2 and then onto the card y. The carriages are held in this position a sufficient length of time to make a good exposure. After the exposure has been made, the carriages are then brought back to their original or normal positions. During the return movementof the carriages, the card rest bar 63 has released the card 3 and permitted the same to drop into the drawer 2. To make repeated exposures upon the ribbon 3 the frame 7 5, provided with the casings 73 and 7 4, for holding the unexposed and the exposed parts of the ribbon, is first lowered into a position indicated by dotted lines in Fig. 2. When the frame 7 5 is in its lowered position, the intermediateportion of the ribbon 3 between thecasings 7 3 and 74, will extend in front of the negative plate 2. Then a similar operation of the carriages 21 and 22, previously described in the process of printing the card 3 is performed. Under plate 2 is placed in a vertical each successive movement of the carriages 21 and 22, the ribbon y is given a step by step movement in front of the negative plate 2. By the use of the curtains 31 and 32, various shades and effects may be obtained upon the prints, when other styles and shades, not found in the rolled curtains, are required. Individual light screens, masks, vigncttersand the like, may beheld between the leaf springs 62 so as to project on either side of the negative plate 2. To make the mask border effect upon the prints, the holding device shown in Fig. 13, is vertically held between the clamps 5 and 6.
